naeaeea To all whom 'it may concern:

Be it known that'l,- donn E. Woonnonr, a citizen of the` United States, residing at Worcester, in the county of llorcester and State ot' Massachusetts, have invented a new and useful Counter lor lntaglio-Presses, of'

this diiculty, itI is subj ect to additional diihf culties owing to the tact that the broad cuts in the intaglio plate7 esyjieciallyl those 'forming the letters, will receive continually increasing projections troni the sott blanket as thesaine `is compacted. This tends. increasingly to cause the ink to he toi-ced out at the edges of the cuts and to malte bad Work.

@ne of the objects of this linvention is to provide for 'reinedying this difficulty and especially to provide ineans whereby the operatorcaii control the operation of the reinedying ineans in accordance With. the conditions existing. Another object of the invenn tion is 'to provide for preventing the addi' tional part of the counter which is used from getting out oii the register. The invention also involves improvements in details of construction of mechanism for printing. Fun

`ther object-s of the invention will appear hereinafter.

l i The invention is shownfas applied' to a 'Well-` known type of intaglio press having a frame 10, `driving shaft 11, and feed mechanism l2 l retenteuneb.5, 1eie.

.for driving a roll 131. which moves a web of i paper alongifor wiping of the plate.l This press alsoes usual is p ovided with a counter support l5, and a punger 16, detailsof which Will not be described as they do not constitute a part of this invention.

. On the counter support is the usual counter block 20 carrying the counter 19, but in addition to this' ordinary construction it is provided with a second portion 21 Which forms a part ofthe counter, and is iiiomliilyA mounted With respect to the main part theref of. This is shown asconsisting ofk a blanket ,or the like formed of suitable blanket material.l It is shown' as being inounted`on. a

rectangular `traine 22 which Vsurrounds the counter. This isf provided :with integral guides 23 extending inwardly and engaging the longitudinal edges OJ'the` inain counter block for a purpose to be described in itull hereinafter.

i This blanket is connected With the fi-aine` by nlamps 2dv which are'held by bolts. y

The hlanketand blanket frame are'held normally toward one side of the press by a 1 spring 25, 'which in this case -is shown ,as also supporting thel end of this frame. The tendencyV of the spring is to torce the counter frame to the right in Figs. 2 and 4. i

Connected .With the other end of the frame is a rod 26'Whicli is pivoted on a crank'27 on a vertical shaft mounted ina bearing 28 on the frame. This shaft is provided 'with an arm 29 for operating it.v The arms ,27 and 29 and the shaft can be made conveniently of an integral piece of Wire ybent into the shape shown. The arin 29 is intended to be operated hy a link. 3() which .is provided with a'- stud 31 connected by la link32 With a crank 33 pivoted on a bracket' 34 on thev frame. vBy

operating. this cranlr the link and conse-4' quently the stud Sloan lbe raised and lowered. l Mounted on the traine is a Stationary plate 35 having a V-shaped slot 36 provided With a socket 37at the top.` Pivoted to this plate on' a pivot 39 is a swinging plate 40. This swinging plate has a slot` 4:15, the bottom of which is just wide enough to receive the stud 31 and the top extends as highy as the socket 37, which also is just large enough to receive thestudf `This plate 10 is connected by a.

4link 42 with an eccentric 43 on the shaftof the roll 13. ,I t y The operationyof this part of the device is as follows: When thestud 31 is at the bottom of the slot 41, the oscillation of the link 42' causes the plate 40 to oscillate and the link A370 to partake of this'motion. This obviously swings the arms 29 and ,Q7 vibrates the rod 26 and the blanket 21 between impressions. If, however, the crank 33 is turned to such a position that ,the stud 31 is vheld up in the notch 37 it is freed from the control of the slot 4:1 and positively prevented from vibrating, although the plate 10 continues to operate as usual.

The purpose of this mechanism is to control fully the conditionl of the blanket and consequently the printing. With the parts in stationary position, it is obvious that the blanket will gradually become harder on the compressed portions but not in the portions which do not come into contact with the plate but only into the engraved lines thereon. When this action continues to such an extent as to force the ink out of the an graved lines andblur'it around the edges the operator will simpl move the crank 3S so as to bring the stu '31 down into the bottom of the slot i1 and then the blanket will vibrate and receive impressions on different portions of these surfaces. This wil*L tend to produce a uniform condition of the blanket and then the operator can swing the crank 83 back and allow the printing operation to go ahead with theblanket in .its original position until the same condition is met with again. When this shifting ac.- tion vfirst takes place some of the iirst impressions may not be perfect and it is only after the result has reached a sufliciently high degree of perfection that the parts are secured in inoperative position so as to continue that character of printing.

It will be observed that the vibrations of the surface of the counter, namely the blanket 21, will becaused to be absolutely rectilinear on account of the guides 23 on frame 22fwhich engage the edges of the counter block 20. In this way the tendency `which the blanket has to shift about laterally is entirely obviated, and the blanket can be brought back exactly to its original po sition, so that the compression previously obtained need not all be lost. Thus goed printing can be done without material waste of time, and the life of the blanket is not' lessened.

Another form inwhich the invention can be carried out is indicated in Figs. 6 and 7. y In this case the numerals l0 and 26 in` `dicateV the same elements as in the other ease. Itisl to be understood that the rod 26 is connected with a construction like that shown in igs. #t and '5, with or without ai, uibdtiieaitions. This rod 55:6 this case is operator changes it.

pivoted to a. bell crank having two arms and 51. These two arms if desired can be secured to opposite ends of a shaft 52. The arm 51 is provided with two notches and 54.

Mounted in convenient position is a pivoted plate 55 adapted to come against either one of two stops 56 or 57 and it is provided with a pivot 58 which is connected by a link 59 with a member 60 on the arm of a controlling rod 61A. This rod is designed to be operated from the eccentric 43 shown in the other figures. The connection between the members 59 and 60 has a projectingvpivot stud 62 at the point of connection.

In the. position shown in Fig. 6 the spring on the right hand end of the blanket tends to hold the rod 26 and consequently the arm 50 to the right and to hold the arm 51 forward. Consequentlyy the vibration of the rod 61 has no tendency to dislodge the pin 58 from the notch 5i in which it is located.

Therefore, when it is desired to prevent vibration of the blanket the plate 55 is brought to the left into contact with the stop 56. When 1t 1s desired to cause the blanket to vibrate, the plate 55 is .moved to the right into Contact with the stop 57 and the notch 54 engages the. stud 62.I In this case the .vibration of the rod 61 causes the arms 50 and 51 to vibrate as will be obvious.

Another way in which the device can be 'the pin 58; This simply moves the blanket over to a second position by slightly raising the arm 51 and it is heldthere until the This-arrangement is provided so that the operator can more the blanket over if in his judgment it needs it either with 0r without the accompanying vibration thereof.

It has been found in practice that by the use of this invention either in the forms shown, or in other formsifor accomplishing the saine purpose the counter can be kept,

by a comparatively `unskilled operator, in

proper condition for the highest class of printing of this difficult type, namely, the printing of both illustrations and reading matter from the same engraved plate and that the moistening of the paper which has also been found to 'be necessary does not introduce anyf'complications that are not overcome by this"i,nvention. I

While I have described my invention in connection with. the production of work of the above character, upon' moistened paper, the invention presents valuable advantages when employedin the production of certainkinds of ordinary die stampin upon dry paper and I do not wish to ber imited to the use of my invention on any* particular class of intaglio Work. v Y
